Hi, Devora -
Independent of heaviness, I prefer using silk for everything. I like
the way it knots and I love the liquid drape of a necklace strung on
There is an exception, though: if the holes of the beads are
native-drilled (e.g., drilled by hand from either side, meeting in
the center of the bead), the quick solution is Softfelx as Beth
says. The longer, more OCD way is smoothing out the drill holes with
a diamond sintered bead reamer…and then stringing on silk. In a
perfect world, beads, pearls, etc., have been drilled by lasers,
which leave one smooth hole.
Do let us know how you make out.
